Degenerate squeezing in a dual-pumped integrated microresonator: parasitic processes and their suppression
Hossein Seifoory, Zachary Vernon, Dylan Mahler +3
Using a general Hamiltonian treatment, we theoretically study the generation of degenerate quadrature squeezing in a dual-pumped integrated microring resonator coupled to a wavegui…
Mitigating linear optics imperfections via port allocation and compilation
Shreya P. Kumar, Leonhard Neuhaus, Lukas G. Helt +4
Linear optics is a promising route to building quantum technologies that operate at room temperature and can be manufactured scalably on integrated photonic platforms. However, sca…
Quantum circuits with many photons on a programmable nanophotonic chip
J. M. Arrazola, V. Bergholm, K. Brádler +36
Growing interest in quantum computing for practical applications has led to a surge in the availability of programmable machines for executing quantum algorithms. Present day photo…
Squeezed light from a nanophotonic molecule
Y. Zhang, M. Menotti, K. Tan +7
Photonic molecules are composed of two or more optical resonators, arranged such that some of the modes of each resonator are coupled to those of the other. Such structures have be…
Broadband quadrature-squeezed vacuum and nonclassical photon number correlations from a nanophotonic device
V. D. Vaidya, B. Morrison, L. G. Helt +13
We report demonstrations of both quadrature squeezed vacuum and photon number difference squeezing generated in an integrated nanophotonic device. Squeezed light is generated via s…
Passive, broadband and low-frequency suppression of laser amplitude noise to the shot-noise limit using hollow-core fibre
Euan J. Allen, Giacomo Ferranti, Kristina R. Rusimova +6
We use hollow-core fibre to preserve the spectrum and temporal profile of picosecond laser pulses in CBD to suppress 2.6 dB of amplitude noise at MHz noise frequencies, to within 0…
A SOI Integrated Quantum Random Number Generator Based on Phase fluctuations from a Laser Diode
Francesco Raffaelli, Philip Sibson, Jake E. Kennard +3
Random numbers are a fundamental resource in science and technology. Among the different approaches to generating them, random numbers created by exploiting the laws of quantum mec…
An On-chip Homodyne Detector for Measuring Quantum States and Generating Random Numbers
Francesco Raffaelli, Giacomo Ferranti, Dylan H. Mahler +7
Optical homodyne detection has found use in a range of quantum technologies as both a characterisation tool and as a way to post-selectively generate non-linearities. So far optica…
Characterizing an Entangled-Photon Source with Classical Detectors and Measurements
Lee A. Rozema, Chao Wang, Dylan H. Mahler +4
Quantum state tomography (QST) is a universal tool for the design and optimization of entangled-photon sources. It typically requires single-photon detectors and coincidence measur…
Quantum Data Compression of a Qubit Ensemble
Lee A. Rozema, Dylan H. Mahler, Alex Hayat +2
Data compression is a ubiquitous aspect of modern information technology, and the advent of quantum information raises the question of what types of compression are feasible for qu…
On the Optimal Choice of Spin-Squeezed States for Detecting and Characterizing a Quantum Process
Lee A. Rozema, Dylan H. Mahler, Robin Blume-Kohout +1
Quantum metrology uses quantum states with no classical counterpart to measure a physical quantity with extraordinary sensitivity or precision. Most metrology schemes measure a sin…
Scalable Spatial Super-Resolution using Entangled Photons
Lee A. Rozema, James D. Bateman, Dylan H. Mahler +4
N00N states -- maximally path-entangled states of N photons -- exhibit spatial interference patterns sharper than any classical interference pattern. This is known as super-resolut…
A Note on Different Definitions of Momentum Disturbance
Lee A. Rozema, Dylan H. Mahler, Alex Hayat +1
In [1], Busch et al. showed that it is possible to construct an error-disturbance relation having the same form as Heisenberg's original heuristic definition[2], in contrast to the…
Adaptive quantum state tomography improves accuracy quadratically
D. H. Mahler, Lee A. Rozema, Ardavan Darabi +3
We introduce a simple protocol for adaptive quantum state tomography, which reduces the worst-case infidelity between the estimate and the true state from to $O(N^{-1…
Violation of Heisenberg's Measurement-Disturbance Relationship by Weak Measurements
Lee A. Rozema, Ardavan Darabi, Dylan H. Mahler +3
While there is a rigorously proven relationship about uncertainties intrinsic to any quantum system, often referred to as "Heisenberg's Uncertainty Principle," Heisenberg originall…
Identification of Decoherence-Free Subspaces Without Quantum Process Tomography
D. H. Mahler, L. Rozema, A. Darabi +1
Characterizing a quantum process is the critical first step towards applying such a process in a quantum information protocol. Full process characterization is known to be extremel…
Self-calibrating Quantum State Tomography
Agata M. Branczyk, Dylan H. Mahler, Lee A. Rozema +3
We introduce and experimentally demonstrate a technique for performing quantum state tomography on multiple-qubit states despite incomplete knowledge about the unitary operations u…
